RELATED APPLICATIONS

The present application is a Continuation-In-Part of InternationalApplication PCT/US94/09968, claiming the priority date of IsraelApplication 106957 filed Sep. 9, 1993.

FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to grilling appliances, and particularlyto an electrical grilling appliance for use in grilling meat products,such as steaks, hamburgers, and the like, in an extremely short time.The invention also relates to food holders particularly useful in suchgrilling appliances.

A large number of electrical grilling appliances are known and describedin the patent literature. The known grilling appliances generallyinclude open grills, racks or meshes for holding the food article to begrilled. However, such grilling appliances usually require aconsiderable period of time to grill a steak or hamburger. Otherappliances are known, such as described in our prior U.S. Pat. Nos.4,762,058 and 5,181,455, which permit food articles to be grilled in arelatively short period of time.

An object of the present invention is to provide a novel simplifiedconstruction of electrical grilling appliance which permits foodarticles, such as steaks, hamburgers, and the like, to be grilled in avery short period of time.

OBJECT AND BRIEF SUMMARY OF THE INVENTION

According to the present invention, there is provided a grillingappliance, comprising: a housing including a vertical food compartmentfor receiving a food article in a vertical position; a heated firstgrill plate mounted in a vertical position in one side of the foodcompartment; a heated second grill plate mounted in a vertical positionin the opposite side of the food compartment; and a drive for driving atleast one of said grill plates while in its vertical position andsubstantially parallel to the other grill plate, to an extended positiontowards the other grill plate, or to a retracted position away from theother grill plate.

According to two described embodiments, the drive includes an electricalmotor for driving the movable grill plate to both its extended andretracted positions. A further embodiment is described wherein anelectrical motor drives the movable grill plate to its retractedposition and a spring return drives it to its extended position.

As will be described more particularly below, a grilling appliance ofrelatively simple structure may be constructed in accordance with theforegoing features to permit food articles, particularly meat products,to be grilled in a very short period of time. Thus, when, e.g., thesecond grill plate is driven to its extended position, it presses thefood article between it and the first grill plate thereby producing highheat transfer between the two grill plates and the food article, whichsubstantially reduces the required grilling time. Moreover, whengrilling an article of greater thickness, the appliance may be designedto apply a larger pressure by the two grilling plates, therebyincreasing the heat transfer to it, and making the grilling time lessdependent on the thickness of the food article.

Further features and advantages of the invention will be apparent fromthe description below.

DESCRIPTION OF PREFERRED EMBODIMENTS

The grilling appliance illustrated in FIGS. 1 and 2 of the drawingscomprises a housing 2 of the general configuration of, but slightlylarger than, a conventional electrical toaster. The housing includes afront wall 2a, a rear wall 2b, opposed end walls 2c, 2d, a bottom wall2e and a top wall 2f. The top wall 2f is formed with an enlargedrectangular opening 4 for introducing the food article to be grilledinto a food compartment 6 within the housing.

A first grill plate 8 is mounted in a vertical position on one side ofthe food compartment 6, and a second grill plate 10 is mounted in avertical position on the opposite side of the food compartment. The twogrill plates 8, 10 are similarly constructed with a metal face plate 12facing the food compartment 6, an internal electrical heater 14, andthermal insulation 16.

Grill plate 8 is floatingly mounted to the housing end wall 2b by aplurality of horizontally-extending coil springs 18. This floatingmounting permits universal angular movement of the grill plate about itsX and Y axes, and further movement about its Z axis (i.e., towards andaway from grill plate 10). Springs 18 are prestressed by an out-turnedflange 20 carried at the outer periphery of grill plate 8, engageablewith an inturned flange 21 carried by a wall of the housing 2.

Housing 2 includes a drive 22 for driving the second grill plate 10 froma retracted position (as shown in FIG. 2) remote from the first grillplate 8, to an extended position towards grill plate 8. Drive 22includes an electrical motor 23 coupled by a transmission 24 to rotate alead screw 26 rotatably mounted between a pair of bearings 28, 30, fixedwith respect to housing 2. A pair of nuts 32, 34 are threaded onopposite ends of the lead screw 26. The threads at the two ends are inopposite directions such that rotating the lead screw in one directionmoves the nuts towards each other, and rotating the lead screw in theopposite direction moves the nuts away from each other. Nuts 32, 34 arecoupled to grill plate 10 by a coupling mechanism which moves grillplate 10 towards its extended position during the rotation of the leadscrew in one direction, and towards its retracted position during therotation of the lead screw in the opposite direction.

Thus, the two nuts 32, 34, are at the opposite corners of aparallelogram 35 which includes four pivotal links 36, 38, 40, 42. Thethird corner of the parallelogram includes a ball-and-socket universalcoupling 44 to grill plate 10 which permits the grill plate to moveangularly in all directions. The fourth corner of the parallelogramcarries a switch actuator 46 for actuating two limit switches LS₁, LS₂fixed with respect to housing 2 on opposite sides of the actuator. Thetwo limit switches are part of a motor control circuitry 47 (FIG. 2),controlling the electrical motor 23. Limit switch LS₁ is located to beactuated by actuator 46 to deenergize the motor 22 when grill plate 10has been moved to its extended position towards grill plate 8, and limitswitch LS₂ is located to be actuated by actuator 46 to deenergize themotor when the grill plate has been moved to its retracted position awayfrom grill plate 8. Housing 2 may include a stop 48 engageable with thegrill plate 10 in its retracted position.

A drip pan 50 is receivable within housing 2 to underlie the foodcompartment 6, and thereby to catch the drippings from the food articleduring the time it is being grilled. Drip pan 50 is insertable into thehousing via an opening formed in the housing end wall 2c, and isprovided with a handle 52 to facilitate introducing and removing it fromthe housing.

A microswitch 53, at one side of opening 4 in the top wall 2f of thehousing, is depressible for energizing the electrical heaters 14 withinthe two grill plates 8, 10, and for energizing the electrical motor 23.The front wall 2a of the housing is provided with a control panel 54which includes an on/off switch 56, an up-time timer button 57, adown-time timer button 58, and a timer display 59 permitting thegrilling time to be pre-selected and displayed.

FIGS. 3 and 4 illustrate one form of food holder 60 which may be usedwith the grilling appliance of FIGS. 1 and 2 for holding the foodarticles within the grilling compartment 6 of the appliance. Food holder60 includes a pair of flexible panels 61, 62 joined at their tops to apair of handles 63, 64, and joined together at their bottoms by aclamping member 65. The sides of the two flexible panels 61, 62 are openso that the two panels may conveniently receive a food article (e.g.,steak or hamburger) to be grilled. Clamp 65, which supports the foodarticle between the two panels 61, 62, includes two jaws 65a, 65bpivotally mounted at one end by a clasp 66 or the like, and openable atthe opposite end by a releasable clasp 67. The outer faces of the twojaws 65a, 65b are bonded to the inner faces of the two flexible panels61, 62. The inner faces of the two jaws are formed with spaced recesses68 defining drain openings to permit draining of liquids therethrough tothe drip pan 50.

The flexible panels 61, 62 may be made of a heat-resistant,stick-resistant plastic, such as "Teflon" (Reg.T.M.), or of a flexiblemetal sheet material (e.g., aluminum) coated with such a heat-resistant,stick-resistant plastic. The dimensions of the flexible panel 61, 62 arelarger than the dimensions of the two grill plates 8, 10, whereby theyalways completely cover them and keep them relatively clean. The overallthickness of the clamping member 65 is less than that of the foodarticle to be held by the holder 60 so that the flexible panels 61, 62better conform to the outer shape of the food article. A pair ofremovable splash guards 69 (FIG. 1) straddle the ends of the two grillplates 8, 10 on opposite sides of the food compartment 6.

The manner of using the grilling appliance illustrated in FIGS. 1 and 2,including the food holder of FIGS. 3 and 4, will be apparent from theabove description. Thus, the movable grill plate 10 is initially in itsretracted position, as shown in FIG. 2, with respect to the foodcompartment 6. The food article (e.g., a steak or hamburger) to begrilled is placed between the two flexible panels 61, 62 of the foodholder 60, and the food holder is then introduced into the foodcompartment 6. The food article is suspended in the food compartment bythe two handles 63, 64 engaging the outer surfaces of the housing topwall 2f on opposite sides of the opening 4. The microswitch 53 isactuated by one of the handles to energize the electrical heaters 14within the grill plates 8, 10.

Switch 53 also energizes motor 23 to rotate lead screw 26. This movesgrill plate 10 towards grill plate 8, and thereby firmly presses thefood article between the two grill plates. Grill plate 10 is driven tothis extended position until switch actuator 46 carried by theparallelogram 35 actuates limit switch LS₁, to deenergize the motor.

As grill plate 10 presses the food article against grill plate 8, grillplate 8 is permitted to move about all its three orthogonal axes byvirtue of its floating mounting (coil springs 18) to the housing; andgrill plate 10 is permitted to move about its two orthogonal axes byvirtue of its ball-and-socket coupling 44 to the parallelogram 35. Grillplates 8, 10 are thus free to move to conform to the surface of thearticle being grilled within the food holder 60 as these grill platesapply pressure to the food article.

The firm pressure applied by the grill plates 8, 10 against the foodarticle being grilled provides good heat-transfer from the grill platesto the food article, thereby speeding up the grilling process. Themounting springs 18 increase the pressure applied by the grill plates tothe food articles with food articles of increased thickness, therebymaking the grilling time less dependent on the thickness of the foodarticles.

When the grilling process has been completed, as preset by the timer,motor 23 is reenergized in the reverse direction, thereby retractinggrill plate 10 until switch operator 46 actuates limit switch LS₂.

FIGS. 5-7 illustrate a one-time use food holder to be disposed after asingle use. In this case, a single sheet is folded at a midportion todefine a pair of flexible panels 71, 72, joined at their bottoms 73. Theupper ends of the two sheets may be stiffened with cardboard strips todefine handles 74, 75 which project outwardly of the appliance housing 2when the food holder, including the food article held thereby, isinserted through opening 4 into the food compartment 6. In this case,the opposite sides of the flexible panels 71, 72, are joined together,as shown at 76 and 77 in FIG. 7, to produce a pocket for receiving thefood article. This pocket is partially closed by a plurality of clips 78extending through the two panels 71, 72, or by spots of adhesive or spotwelds, adjacent the folded bottom 73, to define another compartment 79for receiving the drippings from the food article.

FIGS. 8 and 9 illustrate a modification in the coupling mechanism ofFIG. 2 coupling the grill plate 110 (corresponding to grill plate 10,FIG. 2) to the two nuts carried by the lead screw 112 rotatably mountedbetween bearings 113a, 113b, such that the grill plate is moved towardsits extended position during the rotation of the lead screw in onedirection, and towards its retracted position during the rotation of thelead screw in the opposite direction. The two nuts, shown at 114, 116 inFIG. 9, are each part of a nut assembly, 118, 120, respectively. Eachassembly provides a force-yieldable coupling to grill plate 110, such asto yield when grill plate 110 forceably presses the food article againstthe other grill plate (8, FIG. 2).

Thus, each nut assembly 118, 120 includes a housing 122, 124 enclosingits respective nut and axially movable with respect thereto. Eachhousing 122, 124 is closed by an apertured end cap 126, 128, throughwhich the lead screw 112 passes. A coil spring 130, 132 is interposedbetween the cap and nut of each assembly for urging the housing in theoutward direction with respect to the nut.

A first pair of links L₁ are pivotally coupled at one of their ends tonut housing 122, and a second pair of links L₂ are pivotally coupled atone of their ends to nut housing 124. The opposite ends of the two pairsof links are pivotally coupled to one end of a third pair of links L₃,and the opposite ends of the latter links are pivotally coupled to grillplate 110.

A limit switch LS₁ is located to be actuated by an actuator 134 carriedby nut 114. Actuator 134 projects through a slot 136 in housing 122 andactuates switch LS₁ upon the yielding of spring 130 a predeterminedmagnitude. Limit switch LS₁, as limit switch LS₁ in FIG. 2, deenergizesthe electrical motor (23, FIG. 2) in the extended position of grillplate 110. A second limit switch LS₂ (FIG. 8) is actuated by the pivotalends of the three pairs of links L₁, L₂, L₃ to deenergize the motor inthe retracted position of the grill plate.

The coupling mechanism illustrated in FIGS. 8 and 9 operates as follows:

As in the grill-coupling mechanism illustrated in FIG. 2, the two nuts114, 116 move towards each other during one direction of rotation oflead screw 112, and away from each during the opposite direction ofrotation of the lead screw. In this case, however, when the drive motor(23, FIG. 2) is energized to drive lead screw 112 in the directionmoving the two nuts 114, 116 further apart, the links L₁, L₂, L₃ areeffective to move grill plate 112 to its extended position, i.e.,towards the other grill plate (8, FIG. 2, rather than to its retractedposition as in FIG. 2) with the food article between the two grillplates. As soon as grill plate 110 presses the food article againstgrill plate 8, the two springs 130, 132 begin to yield according to theforce applied against the food article. Yielding of spring 130 causesswitch actuator 134 carried by nut 114 to move towards limit switch LS₁,such that when this yielding has attained a predetermined magnitude, thelimit switch LS₁ is actuated to deenergize the electrical motor in thisextended position of grill plate 110. The motor is deenergized in itsretracted position by limit switch LS₂ (FIG. 8).

This arrangement provides a number of advantages over the arrangementillustrated in FIG. 2. Thus, the extended position of grill plate 110 isnot determined by a fixedly-located limit switch (LS₁ in FIG. 2), butrather is determined by the application of a predetermined force by thegrill plate 110 to the food article while pressing it against the othergrill plate (8, FIG. 2).

Moreover, this predetermined force varies with the thickness of the foodarticle being grilled. Thus, the force applied by grill plate 110 to thefood article in order to cause the two springs 130, 132 to yield,increases in an inverse relation to the distance between the two nutassemblies 118, 120 of the two springs 130, 132. Therefore, themagnitude of the force applied by grill plate 110 against the foodarticle when the grill plate is in its extended position will be largerwhen relatively thick food articles are being grilled (as the two nutassemblies will then be closer together) than when thinner food articlesare being grilled. This accelerates the grilling of relatively thickfood articles, thereby making the grilling time less dependent on thethickness of the food articles being grilled. If the thickness of thefood article decreases during the grilling process, the motor will beenergized to maintain the pressure.

FIG. 10 illustrates one example of an external appearance that agrilling appliance constructed in accordance with the present inventionmay take, particularly one including the coupling mechanism illustratedin FIGS. 8 and 9. Thus, grilling appliance 140 includes a housing 142formed with a large rectangular opening 144 in its top wall forintroducing the food article to be grilled. Opening 144 is straddled bya pair of electrical switch operators 146, 148, both of which must bemanually depressed in order to energize the electrical heaters and theelectrical motor in the appliance. Thus, whether using the food holderillustrated in FIGS. 3 and 4, or the one-time use food holderillustrates in FIGS. 5-7, the two handles of the food holder must bepressed against the two switch operators 146, 148 in order to energizethe appliance. This is a safety feature to lessen the possibility of anoperator accidentally having a finger or hand within opening 144 at thetime the appliance is energized.

The appliance illustrated in FIG. 10 further includes a presettabletimer 150, a display 152, displaying the preset time, a pilot lamp 154energized to indicate the appliance is on, and a second pilot lamp 156energized to indicate that the electrical heaters are operating. Housing142 is further provided with ventilating openings 158, 160.

FIGS. 11-13 illustrate another drive system, generally designated 200,within the housing, schematically indicated by its frame 202, fordriving grill plate 210 with respect to the stationary grill plate 208defining the vertical food compartment 206 receiving the food article tobe grilled. Both grill plates 208 and 210 are constructed as describedabove with respect to FIG. 2, namely including a metal face plate (12,FIG. 2), an internal electrical heater (14), and thermal insulation(16). The stationary grill plate 208 may be floatingly mounted to thehousing frame 202 by coil springs, corresponding to coil springs 18 inFIG. 2, or may be directly mounted to the housing frame.

The movable grill plate 210 is mounted to the housing frame 202 by fourcoil springs 211-214, fixed between the outer periphery of the grillplate, i.e., at its four corners, and the housing frame 202. The fourcoil springs 211-214 serve as a spring drive for driving or urging themovable grill plate 210 to its extended position, i.e., towards thestationary grill plate 208.

Grill plate 210 is driven to its retracted position, away from thestationary grill plate 208, by an electrical motor 216 via a cable 218fixed at one end to the center of the grill plate, and at its oppositeend to a drum 220 coupled by gearing 222 and 224 to motor 216. Drum 220is formed with converging sides for retaining the cable on its outersurface. Gearing 222 and 224 are preferably designed so that drum 220 isrotated about 270° to drive grill plate 210 from its fully extendedposition slightly spaced from the stationary grill plate 208, to itsfully retracted position. The drum 220 includes an actuator 226 (FIG.12) engageable with two limit switches LS₁, LS₂ to terminate theoperation of the electrical motor 216 at these two limit positions.

A roller 228 engages cable 218 between drum 220 and the driven grillplate 210, and is urged by spring 230 to take-up the slack in the cable.The movements of the driven grill plate 210 are guided by a pair of pins231, 232 on its opposite sides, movable within slots 233, 234 formed inthe housing frame 202.

In operation, grill plate 210 is driven to its fully retracted position,away from the stationary grill plate 218, by electric motor 216 viacable 218 wound on drum 220. Grill plate 210 is driven or urged in thereturn direction, i.e., to its extended position towards the stationarygrill plate 208, by the return springs 211-214 which were previouslyloaded, during the retraction of grill plate 210 by electrical motor216. During this movement of grill plate 210 towards the stationarygrill plate 208, a food article received within compartment 206 will becompressed under the force of the previously-loaded springs 211-214while the food article is heated. Since the force exerted by springs211-214 is in direct relation to the deformation of the springs, alarger force will be applied to thicker food articles, such as steaks,than to thinner food articles, thereby accelerating the cooking of thethicker food articles. The springs 211-214 may be cylindrical (linear)springs, or conical (non-linear) springs.

FIGS. 14-16 illustrate another construction of multiple-use food holder,generally designated 260, including two flexible panels 261, 262,preferably of a heat-resistant, stick-resistant plastic sheet, such as"Teflon". The rear panel 261 may be thicker (e.g., 0.5 mm) than thefront panel 262 (e.g., 0.1 mm), and may be bonded to the front panel byultrasonic welding along its folded-over ends 263, 264, and also alongits bottom 265. The two panels 261, 262 are bonded at their upper endsto handles 266, 267 of heat-resistant plastic or metal.

The food holder illustrated in FIGS. 14-16 further includes a spacermember, generally designated 268 (FIGS. 15, 16) for supporting the foodarticle FA (e.g., hamburger, steak, etc.) within the food holder butspaced from its bottom 265 to permit the drippings to accumulate in thebottom. Thus, spacer member 268 includes a U-shaped socket 268a at itsupper end for receiving the food article FA, and a curved leg 268b atits lower end engageable with, and spacing the food article FA above,the bottom of the food holder.

Spacer member 268 is preferably made of two stainless steel strips 270,280, joined together at a straight juncture section 271, 281, by contactwelding points 268c. Each strip is formed with a plurality of upstandingfingers 272, 282 at its upper end which together define the U-shapedsocket 268a for receiving the food article. The lower end of each stripis formed with a semi-cylindrical curvature 273, 283 which togetherdefine the curved leg engageable with the bottom of the food holder forspacing the food article above the bottom. This space serves as acompartment 275 for receiving drippings from the food article as it isbeing grilled.

While the invention has been described with respect to several preferredembodiments, it will be appreciated that this is set forth merely forpurposes of example, and that many variations may be made. For example,instead of having an electrical motor drive for driving one grill plateto both its extended and retracted positions, or an electrical motor fordriving it to its retracted position and a spring for driving it to itsextended position, as described above, the appliance could include amanual drive for driving the grill plate to its retracted position, anda spring drive or manual driving for driving it to its extendedposition. In addition, both grill plates could be driven, towards oraway from each other, rather than only one. Many other variations,modifications and applications of the invention will be apparent.
